Chemical (CAS No.)	Reference	Occurrence
Bromodichloroacetic acid (71133-14-7)	NTP (2015)	Bromodichloroacetic acid can form when water containing natural organic matter and bromide is disinfected with chlorine-containing oxidizing compounds.

The action is being proposed under the authoritative bodies listing mechanism, based on a 2015 National Toxicology Program (NTP) report on the substance. Comments are welcome to be submitted before 27 June 2016.
The Prop 65 compliance procedures are quite complicated. Prop 65 itself sets no limits for hazardous substances but only safe harbour levels. While substantial data are required from businesses to apply such safe harbour levels. Currently, Prop 65 regulates hazardous substances in products as per limits and test methods provided in the existing lawsuits or settlement agreements for the same product category. C&K Testing advises businesses to choose professional testing team to test hazardous substances as per test plans recommended by Prop 65 cases.
